Civil engineering design software "Drainage Design / Drainage Design (Light Version)"

Calculate the catchment area and channel length, and compute the rainwater runoff! Based on this runoff, we will determine the flow capacity of the drainage section.

"Drainage Design / Drainage Design (Light Version)" is a civil engineering design software that can determine the flow capacity of drainage sections set in each watershed. It also allows for the examination of flow through culvert sections, the spacing of drainage inlet installations, and the calculation of underground drainage volume. Furthermore, flow velocity calculations can be selected from the "Manning's equation" or "Culvert equation." 【Features】 ■ Calculates catchment area and flow path length by setting the catchment area, and computes rainwater runoff volume. ■ Based on the runoff volume, it can determine the flow capacity of drainage sections. ■ Allows for the examination of flow through culvert sections, the spacing of drainage inlet installations, and the calculation of underground drainage volume. ■ By registering, you can call up sections when inputting "runoff volume," "flow capacity," and "culvert flow." (Sections that can be registered) - Rectangular (Hanch, r-shape, invert) - Circular - Standard horseshoe - Arbitrary horseshoe - Hollow (I) - Hollow (II) - U-shaped (r, Hanch, bottom R) - U-shaped (U-shaped ditch, bench flume) - Free slope ditch - Road gutter - DO pipe - Oval pipe * For more details, please refer to the PDF materials or feel free to contact us.
